Study Guide

Comets

A comet is a loose collection of ice, dust, and small rocky particles that, in contrast to an asteroid, has an extended atmosphere surrounding the center. When passing close to the Sun, this atmosphere warms and begins to release gases forming a visible coma or tail.

Element

An element is matter than cannot be separated into different types of matter by ordinary chemical methods.

First Law of Motion

Also known as the law of inertia, Newton's first law of motion states that An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

Liver

The liver produces bile which emulsifies (separates) fat.

Minerals

Small quantities of certain minerals like iron, calcium, magnesium, and salt are important for nutrition and health.
